To an whom it may ounce 1w,

e it known that I, GEORGE G. lUnonLL, a citizen of the United States, and resident of the city of New York, borough of Brooklyn, county of Kings, and State of New ork, have invented a new and Improved Shaft Attachment, of which the following is a full, clear, and exact description.

My invention relates to a shaft attach; ment, and aims to provide certain new and useful improvements in connection with a device of this character.

It is a well appreciatedfactthat it has been a customary expedient to provide a shaft extending throughout the entire length of a building, and. having doors in communication with eachfioor, through which doors waste material may be thrown into the shaft.

It is also well understood in connection with shafts of this character, that fires have often occurred incident to throwing a lighted match or other burning article into the shaft, and in some instances incident to spontaneous combustion.

For the reason that the fire is, in its initial stages, confined to the shaft, a great amount of headway is usually gained before the occupants of the building are aware of its existence, and consequently a large amount of damage is caused.

Aside from the foregoing, it also dif- Iicult to remove large accumulations of waste material which become deposited and packed in the bottom :of a shaft of this nature.

With this in view, I have provided a con struction in the nature of an attachment to a shaft of the type specified, by means of which primarily, any fire will be confined to a limited area. 4

A further object of my invention is the construction of a device of the character stated, by means of which the person having charge of the removal of the waste material from the shaft will be able to effect this removal with the expenditure of but a minimum of energy.

Further objects of my invention will up pear in the annexed specification, taken in connection with the drawings, which latter present one practical embodiment of my invention, and in which;

Figure 1 is a sectional side view taken through a lmilding and, shaft of the type stated, and showing my improved. attachment associated with the latter.

Figure 2 is a perspective view of one unit of my attachment, and showing the same in its normal position, and

Figure 3 is a View similar to Figure 5. but showing the position which the parts assume during the removal of the waste mate-- rial from the shaft.

In these views it will be noted that the reference numeral 5 indicates a building incorporating a shaft 6, which may be in the nature of a dumbwaiter shaft, and is preferably lined with a fire resisting material, such as 7.

Also, the shaft 6 is provided with open ings 8 having any desirable type of closure associated with them, whereby access may be had by the occupants of each floor of the building to the shaft.

Contrary to the conventional construction, however, it will be seen that I aim to provide a number of partitions 9 preferably of metal, which partitions are positioned with in the shaft 6, and thus provide compart ments or sub-divisions within said shaft. It is to be noted that each of the partitions 9 is to be hingedly secured to the inner face of the shaft, and to provide means permitting of this, and at the same time to form a fire proof closure, 1 may conveniently utilize sill members 10 corresponding in number to the number of partitions 9 employed.

Ea ch of these sills provides a hinge 11 with which one of the edges of a partition 9 may be associated, and a connecting member, such as a chain 12 serves to interconnect adjacent partitions with each other, and with any suitable type of actuating member such as a. drum 13.

Thus the drum 13 maybe actuated to of feet a simultaneous raising of all the partitions 9 to the position 2, whereby each of the partitions will form a base capable of receiving the waste material from a floor. Also a bafiie 14 is pref erably provided adjacent the lower end of the shaft 6, and co-operates with a closure 15 which may be swung to the position indi cated in dotted lines so as to close the lowermost opening 8 through which the accumulated material is discharged into any suitable type of receptacle.

It will thus be noted, assuming that the waste material within 1336 shaft 6 becomes indicated in Figure ulated to permit of the partition 9 swinging downwardly to the position shown in dotted lines in Figure 1. This obviously will resuit in all of the waste material. falling through the shaft 7, which will be diverted by means. of the baffle 14: or'other element utilized for this purpose.

Obviously numerous. modifications of structure might readily be resortedto withoutin the least departing from the spirit of my inventiomwhich I claim as;

1. A shaft. attachment including in combination with a shaft, of a plurality of par titions secured within-said shaft and normally'eX tending across and within thesame, and means for simultaneously moving said artitions.

2. A shaft attachment, including in combination with a. shaft, of a plurality of par-.

titions adapted to normally lie transversely of said shaft and extending within the same whereby to form a plurality of compartments, and means for simultaneously moving said partitions.

3. A shaft attachment, including in conibination with a shaft, of a plurality of partitions adapted to normally lie in a horizontal plane and to normally extend into said shaft, whereby each forms a base capable of receiving material deposited within said shaft at various levels, and means for moving said partitions.

4:. A shaft attachment, including in combination with a shaft, of a plurality of par-- titions hingedly secured within said shaft, a

' connecting member extending l'ietween said partitions for inter-connecting the same and permitting of a simultaneous movement thereof, and means for moving said connecting member.

5. A shaft attachment, including in eon:- bination with a shaft, sills within said sha ft, partitions hingedly secured to said sills, and adapted to co-operate with the same to provide substantially fire proof closures. and means for moving said partitions.
